To all 107mm it may concern Be it known that I, BENJAMIN Ko'rnovsnr, a subject of the Czar of Russia, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and Ntate of New York, have invented a new and Improved Button Magazine and Feeding Device, of which the following is a full,

clear, and exact description. l

This invention relates to button magazine and feeding devices especially adapted for use in connection with a staple forming and attaching machine, such as that disclosed in my application for Letters Patent, Serial Number 831,746, filed April 14, 1914, and of which application the present one is a division. However, there are certain features of the invention which are not limited to machines of the-character referred to, but are susceptible to more general use.

The general objects of the invention are to improve the construction and operation of machines of the character referred to so as to be thoroughly reliable and efficient in use, automatic in its various operations, and so designed as to be adapted for use with buttons of different sizes.

A specilicobject of the invention is'the provision of a new forni of button-feeding chute or raceway provided with means for effecting the4 discharge of buttons one at a time therefrom to the staple-forming and attaching mechanism, such means and chute being so designed as to be suitable for buttons of dii-ferent sizes.

Another specific object is to so mount the chute that it can be moved out of operative position and tilted to such an inclination that the buttons will tlow back automatically into the hopper from which the chute is fed, whereby the chute can be emptied to permit its use with buttons of a different size from the buttons in the hopper, the hopper being capable of being adjusted to a position of inoperativeness, so that buttons can be fed to the chute'byhand.

Another object is the employment in connection with an ,oscillatory button hopper, of movable button pick-up means therein and so designed as to`pick up one or more buttons and deliver them to theed chute of the machine in a predetermined position,

all other buttons not in such predetermined position being dropped back in the hopper so that clogging of the feeding system is prevented.

lVth suoli objects in view, and others which will appear as the description proceeds, the invention comprises various novel features of construction and arrangement of parts which will be set forth with particularity in the following description and claims appended hereto.

In the accompanying drawings, which illustrate one embodiment of the invention, and wherein similar characters of reference indicate corresponding parts in all the views, Figure 1 is a side view of the machine with the parts in initial position, the button hopper being shownl in section; Fig. 1a is a detail sectional view on line la-la, Fig. 1; Fig. 2 is a view similar to Fig. l, showing the hopper in lowered or -idle position, as when a feed chute is being fed by hand with a style of button different from that in the hopper; Fig. 3 is a view showing the staple bender and driving elements at the end of their working strokes and a button attached to a shoe or other article by the staple thereof being clenched and another button ready to Abe delivered to the staple mechanism; Fig. 4 is a fragmentary plan view of the button feeding mechanism,`the cover of the hopper being open; Fig. 5 is a side view of the button pick-up means in the hopper for selecting the buttons and feeding them to the button chute; Figs. 6 and 7 are sectional views, with the parts in different positions, to show the manner of picking up buttons and dislodging those buttons which are in improper position to enter the chute, Figs. 8 and 9 are face views respectively of the two plates forming the button pick-up der vice in the hopper.

Referring to the drawings, 1 designates the table or shelf of the machine, which is formed with a hub 2 that is suitably fastened to the upper end of a hollow standard or column 3 provided at its lower end with a suitable tripod or base frame (not shown), and extending through this oolumnisan operating rod 4 that has its lowg; end connected with a depressible spring-raised treadle (not shown) whereby power is applied to the machine for operating the various in- B that receives buttons from a hopper C in which'is a button pick-up means D, which oscillates in a vertical plane in the hopper C, sothat buttons can be taken out by the device and delivered to the chute B. At the lower end of the chute is a combined staple- ,forming and driving mechanism E to which buttons are fed from the chute by an ejector F and a star wheel G.

The feed chute or raceway B comprises a pair of vertically disposed ytriangular plates 5 and 6 which are secured together inspaced relation, so that the inclined upper edges 7 will form a raceway for the buttons to slide down, and by spacing the plates 5 and 6 apart a longitudinal groove is provided in this raceway for the Shanks or eyes of the buttons.4 A guard 8 extends longitudinally of the raceway and is 4spaced above the edges 7 so that it is impossible for the buttons to be thrown out of the raceway, such guard bein fastened to the plates of the chute by brac ets 9., At the lower end of the chute and formingextensions of the yedges 7 of the plates of the chute are springs 10 which support the buttons as they are being conducted from the 'chute to the staple-forming mechanism, the springs being yielding so as to accommodate buttonsof different sizes. Reciprocating over this yielding extension of the chute formed bythe springs 10 is button in the chute so as to eject such but` the ejector F, which has a bifurcated lower extremity 11 which is adapted to engage slightly above the center of the lowermost ton as the ejector moves ldownwardly from the position shown in Fig. 3. This ejector is slidably mounted on the lower end of the button guard 8, and on this guard is a stop or gate element 12 in the form of a spring extending over the buttons and having its lower end free so as to yieldingly hold the buttons in the chute. 0n the guard is a pin 13 arranged with its lower end bearing on the spring 12 and the upper end of the pin is adapted to be engaged by a cam surface 14 von the ejector, so that as the latter is.

moved to eject a button the cam 14 will press the spring downwardly so that its free extremity will be in the path of the descending next button as the lowermost button is being forced out by the ejector F. This'tensioning of the spring bythe pin 13 does not take place until after the lowermost button has passed out of gripping relation to the spring or gate 12. The reciprocation of the ejector is performed by a toothed segment 15 pivoted'at 16 on extension lugs 17 of the guard 8, and the teeth. of the segment mesh with rack teeth 18 on the ejector. The segmental gear 15 is provided with an arm 19 formed with parallel lugs 20 between which that -the button ejector will be operated to i eject a button in timed relation to the said mechanism.

'The button feeder or star wheel Gr is lo-l cated between the button ejector and stapleforming mechanism and is mounted on a shaft 28 journaled in a' bearing 29, and on thisshaft is a ratchet wheel 30 with which engages a pawl 31 pivoted at 32 on an arm 33 loosely mountedon the star wheel shaft 28. The pawl-carrying arm 33 is connected by the pivot screw 34 with the link 22, as clearly shownin Fig. 3, so that as the link moves back and forth it will oscillate the pawl-carrying arin and move the pawl 31 into engagement with the successive teeth of the ratchet wheel 30 to move the same step by step, and consequently move the star button feeding wheel in the same manner. A spring-pressed pawl 35, Fig. 2, also engages the ratchet wheel so as to prevent back travel thereof. The star wheel G moves one step with each ejecting movement of the ejector F, and the teeth or arms 36 of the star wheel successively engage buttons to deliver them to the staple-forming mechanism. The button holder H, which holds the button in position toA receive a staple wire or blank. is an approximately rectangular frame having its side members 37 spaced apart with their rear ends fulcrumed on the screw pivot 38 which passes through recesses 39 in the plates 5 and 6 of the button chute B. the screw being fastened in a bearing 40, Fig. 3. The lower portion of the star wheel lies between the side members 37 of the button holder. and the ejector F moves downwardly between these members in ejecting a button. The under side of the holder H near its free end is provided with an approximately semi-circular recess 41 which is adapted to receive the head of a button when the latter is in staplereceiving position. as shown by ,the dotted lines in Fig. 3, whereby the button is held properly in place. The star wheel G moves the button from .the ejector toward the button-receiving recess 41. The head of the button during this movement from the ejector first slides on the resilient members or springs 10 and thereafter on the top surface of the staple bender 42 and staple driver 43. The holder H is provided with a button retainer or guide 44 which embodies a pair of rearwardlyv and upwardly maarre.

' -eiving position the staple driver is h a ut-ton shank-engaging elenged in tlml slot 49 which is proin th driver for allowing the shanks of the buttons to pass into staple-receiving position. rhis element 48 is adapted to yield to ovv the shanks of the buttons to pass alor v the star Wheel, and as soon as the shai rs pass the tip e9 of the element e8, the r is thrown upwardly by a spring G acting on this element, and consequently as the driver moves forwardly to drive a'staple, the element 4S will at the same time carry the next button into position to 'be received by the holder H, so that when the parts of theY staple forming the driving mechanism return to normal position, the butt-on will be ready to receive a staple Wire from the Wire-feeding mecha` nism. immediately after receiving the Wire the bender comes into play to form the staple, and thereafter the driver acts to drive the staple into the fabric and attach the button. The feeding movement of the star Wheel occurs as the drivervis nearing the end of its backward stroke and causes the button to assume a position Where the shank will be in iront of the element 48, so that ivith the next stroke of the driver a button Will be moved to staple-receiving posi tion, ivhile at the same time a button-supplied staple will. be attached to the shoe or other article.

To permit access to' the button-feeding means, as .vell as to the staple-forming mechanism, the feed chute B is pivotally mounted on a pivot 5l on the rear upperv corner of the l'raine and consequently the chute can be tilted to the dotted-line position, Fig.` 2. A catch 52 is arranged to lock the chute in normal position. This catch is mounted on a pivot stud 53 and has a pin which passes through a bearing bracket 55 on which the chute is pivoted, and this pin is adapted to engage with the chute to hold the same in normal position. By pressing the handle 5G of the latch 52 against the tension of the spring 57, Fig. .4, the' latch can be released so that the chute can be moved to the dotted-line position, Fig. 2. In throwing out the chute in this manner the pin 2l on the link 22 disengages the ejector which is carried by the chute retainer being Vpivoted at 45 and wheel in moving the button to sta-A vvhile the link 22 remains in position. This throwing hack of the chute B is also made use of to empty the chute of its buttons, as the buttons in the chute will slide back into the hopper C, so that the chute can be used for the hand feeding of buttons of a diii'en ent size from the buttons in the hopper, it being understood that the hopper will, during the hand feeding, remain in the fullline position, Fig. 2, so that buttons can be placed in the upper end of the chute Witl out the hopper interfering.

To prevent the buttons in the chute from emptying outv as the chute is beinffthrovvn back, an automatic gate or stop device 58, F ig. 3, is employed to move into engagement with the button in the lov'ver end of the chute and prevent the button from sliding out. This device 58 is pivoted at 59, and its button-engaging tip 60 is normally retracted out of the path of the buttons in the chute by the extremity 6l engaging an abutment G2 which is stationary with respect to the table or frame of the machine. A spring 63 carried b v the chute. presses on. the gate device 58 so that when the chute begins to move out of its normal position the tip 60 of the gate device Will move into the feed groove of the chute or raceWay and engage the shank ot the button in the bottom or" the chute. It will thus be seen that the gate device 5S is automatically closed and opened with the movement of the chute from or to operative position.

The hopper C is a metal or other boX hav ing a cover 6:1. The front vvall 65 of the hopper has an opening '6G which is adapted to aline with the chute B, so that buttons can pass out of the opening into the chute. The bottom G7 slopes downwardly from both sides, and in the center isprovided with a slot G8 through Which the button pick-up device Works up and doivn. The button pick-up device comprises a pair of vertically sliding plates G9 and 70. The upper edges 7l of the plates are beveled invvardlv so as to better pick up the buttons in the hopper, and these plates are spaced apart to provide a longitudinal groove 72 betvveen them to accommodate the Shanks or eyes of the buttons while the heads of the latter rest on the upper edges 7l of the plates, and these plates When fully raised are in alinement with the chute, so that the buttons can iiow b v gravityJ down the 'plates and into the chute through the opening in the front ivall of the hopper.

The pick-up plates G9 and 70 are actuated respectively b v levers G9a and 70a connected by a horizontal shaft 7l journaled in the upper rear corner of the frame A. These levers have on their upper rear ends pins Gil" and h movable in slots 72 and 73 on the plates 69 and 70, respectively, the said slots being of diderent configurations and 'so displates will cause the posed that as the levers 69a and 70a are oscillated the plates will move up and down in the hopper, but at differential rates, so that at a mid point in the travel vthe plates will occupy the relative postion shown in Fig. 7, and any button in improper position for feeding into the chute will be dislodged. When the plates are in their lowermost position they have their upper edges 7l opposite each other, and when the plates are in their uppermost position "iis alinement also oecurs, as shown in Fig. 6. To assist in dislodging those buttons which are not in position for feeding i to the chute from the pick-up device, the lttter is provided with a kick-off element 74: in the form of a plate arranged in the outer face of the plate 70 and mounted to swing upwardly on a center 75, where the kick-off device is pivotally connected with the plate 70. This plate projects upwardly upon the top edge 71 of the plate 70 as the pick-up device moves, as shown in Fig. 7, and thereby dislodges buttons which do not have their shanks in the slot 7 2, whereby such buttons are kicked ofl'. Between the plates 69 and 70 is a gate element 76 which is swung from the pivot and is connected by a link 77 with a lever 78 swinging on a fulcrum 79 carried by the plate 70. -On this lever 7 8 is a pin 80 which engages in a slot Sl in the plate 69, whereby the differential movement of the free end of the gate element 76 to move upwardly to aposition where it will hold the buttons from sliding downwardlyfas the piek-up device D moves upwardly toward discharge position, and as its full discharge position is reached the gate element 76 is swung downwardly so as to be out of the'path of the buttons as they slide down the inclined top edges 71 of the pickup plates 69, 70. The kick-oftl plate 74 has a projection 82 which forms a. stop ror gate element to prevent buttons from feeding out of the pick-up device prematurely,l but. this lug is moved downwardly below the level of the top edge of the plate 70 when the pickup device is fully raised and readaY to discharge the buttons into the chute.

Another button kick-oil device 70d, F 5, G and 7, is employed to dislodge buttons improperly positioned on the plate 69.- rl`his device is disposed between the plates 69 and 70 with its top edge below the top edge 71 of plate 70, and it is secured to the latter by a pin 70e or other means. Due to the differential movement of the plates 69 and 7 0 it will be at an intermediate point in the upward movement of the button pick-up means D, that the device 70d will project above the top edge 7l of the plate 69, so that the buttons that have their shanks disposed between the device 7 Od and plate 70 will be retained while other buttons on the plate 69 will be entered dislodged. The kick-off device 7 4 moves up and down with the gate element 7.6. Any suitable means may be used to connect these parts together, such as pins 76a and 76", Figs. 5, 6 and 7.

he hopper G is adapted to have an up and down oscillatory movement, and for this purpose it is provided with forwardlyextending arms S3 which are disposed at opposite sides of the chute B and are pivoted thereto by a horizontal pivot Se which also serves as a pivot for the forwardly-extending arms 69c and 70c of the pick-up plates G9 and 70, the arms of the said latter plates being disposed between the plates forming the button chute. -The hopper is adapted to drop by its own weight after the pick-up plates have moved to their lowermost. position, and is adapted to be raised by theI button pick-up device as the same moves upwardly, and for this latter purpose the plate 69 has a projection 85 on which the bottom of the hopper rests as the pick-up device D is moved upwardly by the levers G9n and 7 0a. A trip lever 86 is mounted on the frame A and swings on a pivot S7. The upper end of this trip lever or catch has a notch SS in which engages a projection S9 on the. arm S3 of the hopper C, as shown in Fig. l, and on the lower endof thetrip lever is a projection 90 that is located in the path of a projection 91 on the lever 69, so that as the said lever tilts during the downward movement of the button pick-up device D, the trip lever will be actuated so as to release the hopper and allow the same to drop, whereby the buttons in the hopper are agitated, and more eifcctively lodge on the pick-up device. A spring 92 is coiled around the fulcrum and automatically returns the latter to a position where it will engage the projection S9 of the hopper. when the latter is raised, so as to thereby support the hopper in raised position until itis again tripped. The lever G9 for the button pick-up device is connected to alink 93 which is connected'at 9-t with an arm 95 secured to the shaft 96 of the lever J. This arm 95 is loose on the shaft 96 and is adapted to be clutched thereto when the buttons are to be fed automatically to the staple-forming and attaching mechanism. For clutching the parts together the shaft 96 has a disk 97 provided with a notch 98, and a catch 99 pivoted on the'lever 95 is adapted to be engaged in the notch 9S of the disk 97, shown in Fig. l., but when the catch 99 is released, as shown in Fig. 2, the hopper will be in lowered or inoperative position,` so 'that buttons can be fed to the chute by hand while. the rest of the machine will operate as usual, with the exception of -the button pick-up device and the hopper.
